Concept cars are not production cars. There isn't a single car on the market where the hood is bolted shut to prevent owners to self service their vehicles. The hyper cars that require their own maintenance crews aren't even street legal.

Bmw i8. Whilst not technically bolted, it has multiple pull loop releases and no way to hold the hood up without putting screwdrivers through each hinge. It also isnt mentioned in its manual and redirects all servicing to bmw themselves

From previous experience I can tell you now that Bankplank is a highly viable option, there is however a few things that you need to make sure of before you pick this wonderful build;
1. Make sure your support always plays support TF that way you can maximise your gold income, also make sure to inform your jungler that you will infact be taking all of his farm.
2. Although it is appealing to go top lane with bankplank for the sake of your wealth it is much more viable in the mid lane due to easy jungle access.
3. Survival in lane is key to maximising your gold, however you should always max parley first even when losing your lane, if you have to, make your support babysit you.
4. Your ultimate is your greatest assest, with this you may farm across the map, in particular wait until multiple waves reach a turret and ulti away, your AD and top lane are sure to understand your need for the gold.

If you follow all the above steps you should hopefully be able to reach full build by the time your 3 inhibitors are down, and then its your time to crit some faces off. Happy bankplanking!
